The state-of-the-art development of biochar based photocatalyst for removal of various organic pollutants in wastewater.

The use of biochar (BC) as a substrate and dopant in developing composite biochar-based photocatalysts (BBP) has proven to be highly promising in advancing wastewater treatment technology. This review focuses on the development of BBP using agricultural and poultry waste-derived BC to mitigate organ...
